TREADLE.

EPECZFICATION forming part of Letters Patent No. 326,862, dated September 22, 1885.

Application filed August 3, 1885.

To all whom it may concern:

Be it known that I, THOMAS PARKS GoooH, a citizen of the United States,residing at Oakland, in the county of Yalabusha and State of Mississippi, have invented a new and useful Improvement in Hand-Power for all Sewing Machines, Attachable to Treadles, Treadle- Rods, or Shafts, of which the following is a description.

Thisinvention is an improvement in treadles, and has for an object to provide asimple, convenient construction, combination, and arrangement of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a perspective View of the improvement applied to atreadle. Fig. 2 isa detail side view ofthe lever. Fig.3is a detail top view ofthe double-armed base-piece, and Fig. 4 represents the olampingbarin plan and edge View, a variation in the form ofsuch clampingbar being indicated in dotted lines.

The base-piece A is formed of the main bar A, provided near one end with a bolt-hole,a, and having a slot, 0., near its opposite end. At each end this bar is provided with a lateral right-angled arm, 13, which may have a bolthole, 2), near its extremity.

The clamping-bar O is provided near one end with a slot, 0, similar to slot a, and near its opposite end it has an opening, 0, usually a slot, as shown, for the passage of the retaining-bolt D. Between its ends I form the clamping-bar with a depression,0,which may be curved, as sh own,to fit round treadle-shafts, or angular, as indicated, to fit shafts of a similar cross-sectional shape.

I preferably make the lever E in two sectionsan upper or handle section, E, and a lower section, E though obviously thelever may be made in a single piece where so desired. My object in making itin two sections is to permit the adjustment of the handleseotions to suit the size or wishes of different persons. To this end I form the upper end of the lower section with a segmental slot, e, and the handle-section is pivoted at e to the lower section below such slot. A set-bolt, e", connects the two sections and passes through the slot 6. By this construction the handleseotion may be adjusted to and held in any desired suitable position.

(No model.)

The lever has its lower end formed of two arms, F and G, the rear one of which is provided with a hook, f, and the forward one with a foot-piece, 9, having a bolt-hole, g, for the bolt D. The hook f is preferably bent forward; but manifestly it may be bent to the rear when so desired.

In operal ion the clamp-baris placed under the shaft of thetreadle to one side of the foot-rest. The base-piece is placed above the shaft, with its slot and bolt-hole registering with those of the clamping-bar. The lever is now applied, its hook being passed through the slots in the base-piece and clamping-bar and caught below such bar, where it is held by the bolt D,passed through the foot of the lever, the base-piece, and the clampbar. The ends of the arms of the base-piece bear on the foot-rest of the treadle, one on each side of the shaft, and may be secured in such position by bolts.

By the described arrangement it will be seen the power is applied to the foot-rest equally on both sides of the shaft, and friction is thereby in great part avoided, and increased leverage is attained.

I prefer to use the armed base-piece, as thereby the lever may be arranged laterally to the foot-rest, and so as to work alongside the operator. This base-piece may be used on either side of the foot-rest in order to be operated by the right or left hand.

It is obvious that the lever constructed as described may be used without the double armed base piece and the clamp-bar. In this use the hook would be inserted through a convenient opening in the fret-work of the footrest, and the bolt D would be passed through the perforation in the foot of the lever and a coincident opening in the foot-rest of the treadle. As stated, however, I prefer to employ the armed base-piece and the clamp-bar.

Having thus described myinvention,what I claim as new is l. The treadle-lever herein described, having its lower end formed with two arms, one of said arms being provided at its extremity with a hook and the other with a foot-piece, substantially as set forth.

2. A treadle-lever, substantially as herein described, consisting of the lower section formed at one end with arms, having one a hook and the other a footpiece, and at its other end with a segmental slot, the handlesection pivoted to the lower section below the segmental slot, and a setbolt extending through said bolt and connecting the said sections, substantially as set forth.

3. A treadle attachment consisting of the armed base-piece and the clamp-bar, each be ing provided with coincident slots and boltholes near their opposite ends, the lever having its lower end provided with a hook inserted through said slots, and the fastening-bolt inserted through the foot-piece, the base, and the clamp-bar, substantially as set forth.

4. The combination, in a treadle, with the IS shaft and foot-rest, of the clamp-bar arranged under the shaft, the base-piece placed on the shaft above the clamp-bar, and having arms lapped on the foot-rest on opposite sides of the shaft, and a lever, substantially as set 20 T.
